  <p>Text input with number validation and transformation. Sets the <code>number</code> validation
error if not a valid number.</p>
<div class="alert alert-warning">
The model must always be of type <code>number</code> otherwise Angular will throw an error.
Be aware that a string containing a number is not enough. See the <a href="error/ngModel/numfmt"><code>numfmt</code></a>
error docs for more information and an example of how to convert your model if necessary.

<h2 id="issues-with-html5-constraint-validation">Issues with HTML5 constraint validation</h2>
<p>In browsers that follow the
<a href="https://html.spec.whatwg.org/multipage/forms.html#number-state-%28type=number%29">HTML5 specification</a>,
<code>input[number]</code> does not work as expected with <a href="api/ng/directive/ngModelOptions"><code>ngModelOptions.allowInvalid</code></a>.
If a non-number is entered in the input, the browser will report the value as an empty string,
which means the view / model values in <code>ngModel</code> and subsequently the scope value
will also be an empty string.</p>

   If the expression evaluates to a string, then it will be converted to a RegExp
   after wrapping it in <code>^</code> and <code>$</code> characters. For instance, <code>&quot;abc&quot;</code> will be converted to
   <code>new RegExp(&#39;^abc$&#39;)</code>.<br />
   <strong>Note:</strong> Avoid using the <code>g</code> flag on the RegExp, as it will cause each successive search to
   start at the index of the last search&#39;s match, thus not taking the whole input value into
   account.</p>
